3. Silvercar
Silvercar is a luxury car rental service that not only provides fabulous Audis for your trip (fully optioned A4s and Q5s), but the company makes the rental process seamless, which is worth every penny. You can reserve your rental on the Silvercar app, then go straight to pick up your car upon arrival — without waiting in the rental car line at the airport. You can even use the app to unlock your Silvercar when you pick it up. Plus, the company offers fancy Peg Perego car seats free of charge, which makes traveling with the grandkids safer and even easier.

So far, Silvercar is available in 21 locations across the U.S., and has plans for further expansion soon.
